The East-West Schism, or Great Schism, was the split between the Catholic Church, centred in Rome, and the Eastern Orthodox Church, centred in Constantinople. In July 1054 a papal legate, Cardinal Humbert, placed a bull of excommunication on the altar of Hagia Sophia against Patriarch Michael Cerularius, who responded by excommunicating the legates. The event came after centuries of growing division over doctrine, such as the insertion of the filioque into the creed, over the authority of the pope and over language and culture. The split became lasting after the Fourth Crusade sacked Constantinople in 1204. The mutual excommunications were lifted in 1965.
